Simultaneous equation 8x-2y=50

8x = 50 + 2y; 8 (50+2y) - 2y = 50. 400 + 16y - 2y = 50.14y = 50-400; 14y = - 350; y = - 25. 8x - 25*2 = 50; 8x-50=50; x = 1 00: 8 = 12.5

8x - 2y = 50

8x - 8x - 2y = 50 - 8x

-2y = 50 - 8x

-2 - 2

y = 25 - 4x

8x - 2 (25 - 4x) = 50

8x - 50 + 8x = 50

8x + 8x - 50 = 50

16x - 50 = 50

+50 + 50

16x = 100
